Durable electrochromic devices (ECDs) driven at 0.8 V were successfully fabricated by the complementary chromic combination of Fe(II)-based metallo-supramolecular polymer (polyFe) and Prussian blue analogues (PBAs). PolyFe was synthesized by the 1:1 complexing of Fe(OAc)2 and bis(terpyridyl)benzene and served as a cathodically coloring material. Nickel hexacyanoferrate (NiHCF) was revealed to be the best anodically coloring material among three PBAs. The complementary electrochromic (EC) pair of polyFe and NiHCF enabled a dramatic decrease of the driving voltage down to 0.8 V in the ECD. We fabricated two ECDs with liquid or solid electrolytes (L-ECD and S-ECD, respectively) and compared their EC properties. S-ECD showed a color change from blue-purple (0 V) to light yellow (0.8 V) with a transmittance change (ΔT) of 45.1% at 580 nm; the response times were 0.52 s for coloring and 1.03 s for bleaching; the coloration efficiency reached a high value of 627.5 cm2/C. S-ECD showed better durability than L-ECD in the long term stability test up to 10 000 cycles. In addition, a drastic change in transmittance spectrum between 415 and 655 nm in S-ECD aligned with the highest solar irradiance in the visible region. When exposing the S-ECD to solar irradiation, it was calculated that a large solar irradiance (99.6 W/m2) can be attenuated at the colored state (0 V), and only a low power density (0.0243 W/m2) was required to keep at the bleached state (0.8 V).

“…Mo 3d peaks are shown in Figures i and S3f. Mo 3d peaks of MoOHCF film show two partly peaks at 236.1 and 233.0 eV, which belong to Mo 3d 3/2 and Mo 3d 5/2 of MoO 3 , respectively, proving that MoOHCF is molybdate hexacyanoferrate. , For the RGBY film, its Mo 3d spectrum has almost the same structure as MoOHCF film. The O 1s peaks, which is given is Figures e and S3b, also confirm this conclusion.…”

“…As FeHCF film has been confirmed that can be blue and green theoretically, compositing red color changeable electrochromic material in it will contribute to obtain RGB changeable electrochromic properties. MoOHCF, in which M A is Fe and M B is MoO 3 , is brownish red at reduction state and light yellow at oxidation state, has complementary electrochromic properties with FeHCF. , Figure b shows the local coordination structure of MoOHCF. Hence, MoOHCF is chosen as red color changeable electrochromic material for compositing.…”

Although multicolor electrochromic materials and devices have been studied by many researchers, there is still none an inorganic single-layer film that has red, blue, and green three typical color states, while red, green, and blue (RGB) are indispensably for multicolor display. Iron hexacyanoferrate (FeHCF) is a kind of well-studied inorganic electrochromic material with relatively colorful properties and a great family of analogues. In this Research Article, the RGBY film with red, green, blue and yellow four typical color states are obtained successfully by coelectrodeposition of FeHCF and molybdate hexacyanoferrate (MoOHCF). This film contains the electrochromic properties of both components. Moreover, benefiting from its high A+ (alkali cation ions that can insert/extract into/from the framework, such as Li+ and K+) content, the redox process of RGBY film can be fully completed to achieve rich color variation. The absorptivity adjustment range of RGBY film at 730 and 440 nm are 0.81 and 0.43, respectively. The response time of RGBY films varies from 3 to 30 s between states and maintains its optical properties without significant decay during 1000 cycles. Finally, a pixelated electrode and a facile electrochromic device based on RGBY film have been developed to exhibit its high application potential in nonemission display field.

This study developed a framework for commercializing window-integrated photovoltaic (PV) panels along with overcoming the limitations of existing window system. The developed framework determined the optimal window-integrated PV panel among window-integrated PV panels according to 3rd generation PV panel type and visible light transmittance (VLT) by considering three aspects: (i) occupant satisfaction; (ii) energy performance; and (iii) economic feasibility. The developed framework consisted of three steps. First, data on building and window-integrated PV panel were collected. Second, various windowintegrated PV panels were evaluated in three aspects. Third, the optimal window-integrated PV panel was determined through multi-objective optimization.
